Tip: Only taxpayers who were still legally married as of December 31, 2018 are able to file as married, whether jointly or separately.

Filing jointly means you file one tax return. When filing separately, you file two tax returns.

You can compare filing jointly vs. separately with TurboTax's free calculator TaxCaster. It will give you the estimated tax differences when filing either way. It’s up-to-date with the latest tax laws and can estimate your 2019 taxes as well.

The main reason you'd want to file separately is to protect yourself from inaccurate tax information reported by your spouse, or in cases where your spouse refuses to file a joint return (or refuses to file, period) and you don't want to get in trouble.

Also, when you file separately, your refund cannot be seized to pay off your spouse's debts. However, filing jointly as an innocent or injured spouse can head off refund seizures as well.

With all that in mind, you can try it both ways to see which filing status works out better for the both of you. If you do this, also consider your state return; in some cases, the taxes saved on the state return more than makes up for the money lost on the federal, or vice-versa.
